I'm not using my real name, because hopefully this will turn out to be nothing but a silly mistake, but I'm really panicking that I could have an ectopic pregnancy. I am on the pill, but am on my pill free days and I still haven't had a period, and it's six days since my last pill. This has never happened before. But all day I have had an excruciating pain to the right side of my abdomen, really low down. It's literally made me keel over several times today, and I've been unable to walk. I can't get to the chemist anytime soon to get a test. Would it show up anyway if it was ectopic? Sorry to be so paranoid, but I was quite ill last month, and scared that maybe my pill wasn't absorbed properly.
